Title: Improvements in or relating to postmarking-machines
IPC: B41K3/58
Filed: 1930-09-09
Abstract: 360,562. Postmarking -machines. NICOHOSOFF, E., 5, Rue Fouad 1er, Alexandria, Egypt. Sept. 9, 1930, No. 26973. [Class 100 (ii).] In a postmarking-machine, the letters &e. are fed between a set of endless bands and a number of coacting pressure rollers and printing is effected through an ink-ribbon by means of a stamping- block carried by a reciprocating arm and coacting with a stationary platen. The machine may be used for stamping the envelopes or wrappers described in Specification 360,112. Two or more stamping-blocks may be provided operating simultaneously or in succession, and a number of machines may be operated from the same drive. It is stated that in addition to the printed impression on the cover, visible impression is produced on the contents. As shown, a series of feed bands 9 passing around grooved vertical rollers 10, 11 coact with pressure rollers 58 to feed letters 62, pressed by hand against the bands, through the machine: the bands 9 are driven by the roller 11, which is rotated by gearing from a main shaft 4, and the axles of the rollers 58 are arranged in guide slots in a frame 59 under the influence of springs 60. The printing-device consists of a block 23 carried by an arm 20, which is pivoted at 22 inside a gear casing 1 and extends through a slot in a top plate 3 : the arm 20, which is guided by brackets 21 and normally rests against an inclined support 32, is rocked against spring action, so as to provide a rapid succession of impression blows, by means of a rotary escapement wheel 28 engaging a projection 27 on the end of the arm. The letters are supported during printing by a buffer 16 arranged below the bands 9 and adjusted into alignment with the bands by turning a nut 18 engaging a screw thread on a rod 17 fixed to the buffer. The face of the block 16 is slightly inclined to the vertical and the face of the printing-block 23 is correspondingly inclined. Printing is effected through an inkribbon 35 carried by spools 38, 38<1> and passed over tensioning-rollers 39 and guide-rollers 36. A pair of bevel gears fixed to a tubular member slidably mounted on a rotary shaft may be shifted., by means of a hand lever 56, to move either of the gears into engagement with a gear on one of the spools whereby the ribbon may be fed in either direction ; alternatively, an automatic reversing- mechanism may be employed. Printing-surfaces.-The printing-block 23 comprises a permanent part surrounding an inner cylindrical exchangeable part, the latter being placed in position from the back of the block so that recesses in the inner part engage projections on the outer part: a pivoted cover plate engaging the back of the inner part holds it in position.

Title: Improvements in or relating to coin-freed automatic delivery apparatus
IPC: G07F13/00
Filed: 1935-10-03
Abstract: 441,608. Coin-freed apparatus for dispensing powdered material. HANSON, E. C., 34, Southfield Road, Rotton Park, Birmingham. Oct. 3, 1935, No. 27252. Addition to 440,814. [Class 27] The apparatus described in the parent Specification is modified so that the measuring- vessel 4, Fig. 1, is permitted to move from its' filling position, in register with the hopper 1, to its discharge position a predetermined plurality of times for each coin insertion. The slide 3, carrying the vessel 4, has fixed to it a rod 8 slidable in brackets 9, 9a. A sleeve 10 fixed to the rod carries a pivoted pawl 12 held against a stop 12b by a spring 12a. At each actuation of the slide 3 to empty the vessel 4, the pawl 12 rotates a ratchet wheel 13 through the space of one tooth, the ratchet wheel being normally held by a pivoted catch 14 engaging a notch in a flange 13a on the ratchet wheel. After prepayment, the catch is raised from the wheel 13 which can then be rotated step-by-step by reciprocating the slide 3 until the wheel has made one revolution or until the next notch comes under the catch 14, when the flange is provided with several notches. Backward rotation of the wheel 13 is prevented by a pawl 21. To prevent the vessel 4 from being moved partly into register with the hopper and then to discharge position without moving the ratchet wheel, the pawl 12 acts on a spring- controlled arm 22, Fig. 4, having a pawl 22a for driving the ratchet wheel 13. The pawl 12 engages behind the arm 22 before the vessel 4 comes partly into register with the hopper. Coin action, weight ; coin-discharging mechanism.-A sixpence inserted through a shoot 19 drops on to the end 18 of the catch 14 and releases this from the notch in the flange of the ratchet wheel. When the slide 3 is then moved forwards, a finger 20 thereon enters a slot in the end 18 and dislodges the coin, which drops to a money-box, the catch 14 returning by gravity and riding on the flanges 13a until the next notch comes under it.

Title: Improvements in methods of producing sulphur by the reduction of sulphur dioxide
IPC: C01B17/04
Filed: 1935-10-03
Abstract: <PICT:0443008/III/1> A gas mixture containing sulphur dioxide and oxygen is introduced into a gas producer through a revolving grate, the sulphur, carbon monoxide, hydrogen sulphide, or other reducing gases formed being brought, while still hot, into contact with a further quantity of sulphur dioxide and then passed through two or more chambers containing a suitable contact material, said chambers being in series and at different temperatures.  The gas mixture is preheated, fed to the producer 1, and the gases evolved mixed with further SO2 as in Specifications 426,456 and 437,236.  The mixture then passes to a contact chamber 5 maintained for example at 700--1000 DEG  C.  After cooling in the preheater 4, it passes through a second chamber 6, at say 300--600 DEG  C. and is then cooled to condense the sulphur, optionally after purifying from soot. Suitable catalysts consist wholly or in part, or are coated with iron or manganese or their compounds, preferably the hydrates such as bog ores or ferruginous bauxite.  Aluminate cement, i.e. melted cement of high alumina content, preferably admixed with iron or manganese may also be used.  Titanium compounds such as titanic acid may be used, especially at the lower temperatures, and alkali metal compounds such as soda, mainly at high temperatures.  These latter compounds may be introduced into the producer where they are vaporized.

Title: Apparatus for disposal of excrements of birds and beasts and sea food wastes
IPC: C05F3/06
Filed: 1970-06-05
Abstract: 1317061 Sewage disposal apparatus YAMATO SETUBI CONSTRUCTION CO Ltd 5 June 1970 [30 June 1969] 27299/70 Heading C1B An apparatus for the disposal of excrements from animals and birds and sea food wastes and the production therefrom of organic manure comprises an air pipe 2 of specified diameter surrounded by a rotatable cylinder 1 and air discharge means in the form of pipes 5 are fitted to the pipe 2 and project radially therefrom. Air is passed into the cylinder 1 through holes 8 at the top ends of the pipes 5 and discs 9 and 10 respectively are coaxially fitted at each end of the pipe 2 and are loosely housed in the rotary cylinder 1 so as to close the end openings 11 and 12 respectively. The disc 9 carries a hopper 13 for supplying organic materials to the interior of the cylinder 1 and an exhaust pipe 14 for discharge of air and waste gas. The disc 10 has an exhaust pipe 15. If the air pipe 2 has a a diameter d and the cylinder 1 has a diameter D, then in order to ensure that semi-fluid matter 31 does not form a hard core in the centre of the apparatus, the relationship between the diameters should be expressed by the equation d=D- (2A)/(D) where A is the cross-sectional area of the clearance 32 in the cylinder 1. In practice, the larger the air pipe diameter d, the less is the supply rate of the waste to be treated. Therefore it is preferable to modify the equation as follows: d=(2)/(3)(D - (2A)/(D)). The air discharge pipes 5 may be replaced by flat air discharge elements 40, each of which has a triangular body with a passage 42 and sides 45 and 46. The sides 45 and 46 are connected at the top and extend tangentially with regard to the periphery of the air pipe 2. A slit 41 in the wall of the air pipe 2 opens into the passage 42. Each element 40 is provided with one or two air jet holes 43, 44 near the top. Since the sides 45, 46 are narrow, the sticky waste material cannot accumulate on the elements 40, so agitation of the waste is maintained. The cylinder 1 may rotate about the axis of the air pipe 2 and discs 52 and 53, which are somewhat smaller than the discs 9 and 10 may be fastened to the air pipe 2 inside and near the discs 9 and 10. The discs 52 and 53 are loosely encased in an inner cylinder 50 having a multiplicity of air holes 51, so that the openings 11 and 12 at the ends of the cylinder 1 are closed by the discs 9 and 10, while both end openings 54 and 55 in the inner cylinder 50 are closed by discs 52, 53. A hollow space 56 is provided between the cylinder 1 and the inner cylinder 50 and cylinders 1 and 50 are connected together by means of support members 57. The air pipe 2 is provided with air jet holes 61 and 62. The disc 52 is connected with a hopper 13 opening into the inner cylinder and with an exhaust pipe 59.

Abstract: 603,362. Making pipes ; centrifugal casting machines. SOC. ANON. DES HAUTSFOURNEAUX ET FONDERIES DE PONTA-MOUSSON. Oct. 18, 1945, No. 27413. Convention date, Dec. 23, 1943. [Classes 83 (i) and 83 (ii)] A bell-ended pipe 1 is made by centrifugally casting the pipe with an externally flared but internally cylindrical form and then machining away the metal at 2 to form a plane or screwed socket. The end closure 6 for a mould 5 for casing such a pipe has no core portion and has the same inner diameter 3 as the pipe required. It may be secured by screws or wedges 7 directly to the mould. In a modification the closure is rotatably mounted in a support which is movably mounted on a non-rotary part so that the closure can be pressed against the mould for casing and moved away for extraction. The closure 17, Fig. 3, may be mounted in its support 20 by a ball bearing 33 and the support 20 by resilient bearings 21 on a frame 23 pivoted to the part 61, Fig. 4, which carries the mould. The free end of the frame 23 may be locked by a latch 66 which is operated by hand or automatically by the axial movement of the mould causing it to engage a fixed part 69. The closure and the non-rotary part 20 may have ducts 44 ... 49 for cooling fluid and leather packing 51 ... 54 or other cooling means. The mould may be inclined so that the closurer opens by gravity when the catch is released or a spring may be added. In other modifications opening is effected pneumatically or electro-magnetically.

Filed: 1953-10-09
Abstract: 770,894. Radar. BRITISH THOMSONHOUSTON CO., Ltd. Oct. 11, 1954 [Oct. 9, 1953], No. 27857/53. Class 40(7) Relates to a radar P.P.I. carried by a first object for displaying the position of a second object relative thereto, one or both objects being capable of movement, e.g. a ship or aircraft. According to the invention a transparent circular screen is mounted in front of the P.P.I., the screen being rotatable about the centre of the display R and carrying lines A B and C D each tangential to a circle C R of radius R corresponding to the minimum range separation of the two objects without danger of collision, e.g. one and a half miles for ships. In order to test if the second object is moving relative to the first object on a collision course, the screen is rotated into a first position (full lines) in which line AB passes through the response X produced by the second object and is then further rotated into the second position (dashed lines) in which the line CD passes through X. A response track X C1 within the angle AXC<SP>1</SP> indicates danger of collision whereas one outside angle AXC', e.g. XC2, is a safe track. The screen may be pivoted centrally or it may be guided about its periphery; it may be carried on a framework rigidly positioned relative to the cathode-ray tube.

Patent GB-280524-A (GB)
Abstract: 280,524. Naamlooze Vennootschap Nederlandsche Instrumenten - Cie. Nov. 15,1926, [Convention date]. Fire-control d a t a , determining by sighting-devices.- The distance from the gun to a movable target and the angle which the direction of the target from the gun makes with the line joining the gun and the firecontrol apparatus is determined by apparatus at the latter position. This apparatus comprises a plane plate having concentric circles and a connecting line through the centre of rotation upon it, a mark movable parallel to the plane of the plate adjustable angularly and radially, and a mark adjustable in the direction of the connecting line. The base 1 of the apparatus carries a rotatable table 2 supporting a plate 20 having a mark 21 thereon, adjustable radially and angularly with respect to the axis X-X of the apparatus. The setting radially is shown on the scale 34 and corresponds to the base line, fire-control position to gun. It is set angularly from the shaft 15 connected to the sighting telescope following the target. Supported on pillars 35 above the plate 20 is a transparent strip carrying a mark 49 adjustable in the direction of the target by screw 37, 38 by the milled head 44 as shown. The pillars 35 also support a table 36 carrying a slide 50 from which is supported a rotatable plate 75 with concentric circles 77 corresponding to the range. After initial setting by a milled head the position of the slide 50 is determined by the operation of the spindle 64 from the range finder so that the distance from the axis X-X to the centre of rotation Y-Y of the plate 75 correspondes to the distance of the target from the control apparatus. In use, the mark 21 being set in accordance with the base and moved angularly by the sighting- telescope, the plate 75 is set over the axis X-X in accordance with the range and traversed in its slide by the rangefinder through the spindle 64, and then angularly adjusted by the milled head 79 to retain the connecting line 76 over the mark 21. The mark 49 is then observed through the magnifying glass 87 and is continuously adjusted by the milled head 44 to the same concentric circle as that which contains the mark 21. The shaft 78 transmits the angle between the fire-control apparatus and target and target and gun, the shaft 7 the angle between the gun and fire-control apparatus and the fire-control apparatus and the target, from which the angle at the gun may be determined. The range at the gun given by the position of the mark 49 is transmitted by the spindle 71, owing to the shafts 38, 54 being coupled by differential gear 67, 68, 73.
Patent GB-654208-A (GB)
Title: Improvements in or relating to speed regulators for dynamo-electric machines
IPC: H02P7/26
Filed: 1948-10-29
Abstract: 654,208. Automatic control systems for electric motors. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 29, 1948, No. 28095. Convention date, Oct. 30, 1947. [Class 38 (iv)] In an electric motor speed control system, the excitation of the field is automatically regulated in accordance with the deviation of the speed from a datum value. The output of an A.C. tachometer driven by the machine produces a D.C. voltage which is used in opposition to a reference voltage, to bias a triode the current from which develops a second bias voltage which is applied to regulate the current through the rectifiers supplying the machine field. As shown, the speed of motor 10 is regulated through the control of bias to the rectifiers 16, 18, 20 which supply the exciting current to field 14. The bias is derived from resistor 58 which forms the load to triode 138, 142, 146 in which the grid 146 is biassed from the load resistor 153 of the triode 136, 140, 144. The bias of the grid 144 of the latter valve corresponds to the out-of-balance between the reference A.C. voltage developed by tachometer 64 and the A.C. voltage of tachometer 62 driven by 10, both of which voltages are rectified in the double triode valve 82. Response of the system to rapid speed fluctuations is effected by condenser 176 and an antihunting voltage is produced at the secondary of transformer 40 and applied to grid 146.
